Teen stabs 3-year-old little sister to death in Yunlin County: police

TAIPEI, Taiwan -- A 17-year-old girl surnamed Hsu allegedly killed her 3-year-old stepsister with a knife in Linnei Township (林內鄉) of Yunlin County (雲林縣), Yunlin police said, noting that after being questioned by prosecutors, the case is being transferred to a juvenile court for review.

Officials from Yunlin's Police Department Douliu (斗六) Precinct yesterday said that Hsu reported this incident herself, adding that police arrived on the scene directly after Hsu made the report.

Police said that on Tuesday night, the girl allegedly locked herself and her sister in her room, and stabbed her sister to death when her mother was watching television in the living room. Hsu stabbed her 3-year-old sister four times in the heart and torso, police added.

Hsu's mother said she thought Hsu was taking care of her sister in the room, noting that she later discovered that the door was locked and Hsu refused to respond, police said.

Hsu's mother then asked the father to return home as soon as possible, police said, adding that Hsu's father later kicked the door open and discovered the 3-year-old girl covered in blood, lying lifelessly on the bed. Hsu confessed that she stabbed her sister, police said.

The police said that that Hsu's father had an affair three years ago and later brought Hsu's younger stepsister back to their residence to live together.

Yulin police said that the elder sister was always jealous about her younger sister and claimed that her parents loved her stepsister more than her. Hsu also blamed her father's mistress for ruining her family, police said.

Quoting Hsu's statement, police said the suspect had the intention to kill her 3-year-old sister for some time.

According to the investigation, the 17-year-old Hsu studied at a senior high school in Changhua County (彰化縣), police said, noting that Hsu was a good student. Her father is a cook who sells grilled steaks in a night market, police added.
